If anyone buys this thing, thinking it is a projector, they are going to be totally bewildered by it. It is not a projector, it is the light source for a 35 mm film projector.

Flange bearing frog, specifically an OWL (one way low speed). Flange bearing track alignment handles low speed/low traffic side of the diamond while the “normal” side is for the higher traffic side of the diamond.

What I had in mind was, "This diamond crossing is called, "Mulberry Diamond Railroad Crossing," Mulberry, Florida.

I like your answer much better, Chuck.

I didn't even notice that CSX's Valrico Subdivision high speed route had no cut in the rail. The CSX Valrico Subdivision trains run through the diamond at high speed on their tread with no gaps in the rail.

The Bone Valley Subdivision, which serves a number of phosphate mines along its route between Achan and Agricola, crosses the Valrico rails at slow speed by means of raising up on their flanges to cross over the top of the Valrico rails.

Sometimes this is called a Lift or jump frog.

This is another example.
A one-way, low-speed (OWLS) other way high speed, diamond in Champaign, Illinois.
